Features of Silicon Carbide Plate

Silicon Carbide Plate usually refers to a plate made of silicon carbide (SiC) material. Silicon carbide is a composite material that combines the characteristics of silicon and carbon, has many kinds of excellent properties, and is widely used in industry. The following are some of the main features of silicon carbon plate:

High hardness: Silicon carbide has a very high hardness, second only to diamond, which makes silicon carbon plates extremely wear-resistant and suitable for various environments with severe wear.

High-temperature stability: Silicon carbon plate can maintain its physical and chemical properties unchanged at very high temperatures, and the maximum operating temperature can reach more than 1600°C, so it is widely used in high-temperature industries such as metallurgy and ceramic sintering.

Low thermal expansion coefficient: Compared with metal materials, silicon carbon plates have a lower thermal expansion coefficient, which means that they change less in size when the temperature changes, reducing the risk of thermal stress and deformation.

Good thermal conductivity: Silicon carbon plate has a high thermal conductivity and can faster conduct heat, which is ok for application scenarios that require efficient heat dissipation.

Corrosion resistance: Silicon carbide has good resistance to most acids, alkalis and salts and is not easily corroded, which makes silicon carbon plates also have important applications in the chemical industry.

Electrical insulation: Although some types of silicon carbide can be semiconductors, ordinary silicon carbon plates are generally good electrical insulators and are suitable for use as insulating components in electrical equipment.

Lightweight: Compared with traditional metal materials, silicon carbon plates have a lower density, which helps to reduce the weight of the structure, which is particularly important for fields such as aerospace.

Thermal shock resistance: Silicon carbon plates can withstand large temperature changes in a short period without cracking or damage, which is very important in applications with rapid heating and cooling.

Self-lubrication: Some silicon carbide products have a smooth surface and have a certain self-lubricating effect. They can work under oil-free lubrication conditions and reduce maintenance costs.
